Controller-To-Pump Connection; Connection J6 And J7 - Accessories And Options Interconnections - Varian Turbo-V 150HT Bedienungshandbuch

PIN DESCRIPTION
7-14 R2 signal 24 V, 60 mA, optically isolated
output (pin 14 positive, pin 7 negative).
The output Voltage will be present upon the
programmed condition delay YES or delay NO
(see the cycle diagram in the following pages).
If YES is selected, R2 is off and the
is zero over all run up time, then:
a) If running
R2 = OFF
b) If running
R2 = ON
If NO is selected:
a) If running
R2 = OFF
b) If running
R2 = ON
8-15 FAULT signal 24 V, 60 mA, optically isolated
output (pin 15 positive pin 8 negative).
The output Voltage will be present when a fault
condition is displayed on the front panel
display.
1-9 Analog output voltage (0 - 10 V) propor-tional
to pump speed (pin 9 positive, pin 1 negative).
The following figure shows a typical logic output
connection (relay coil) but any other device may be
connected e.g. a LED, a computer, etc., and the related
simplified circuit of the controller.

Controller-to-Pump Connection

A five-meter long cable is provided to connect the
controller to the pump. The following figures show the
controller output connector configuration where pins:
•
A-F = pump temperature sensor
•
B-C-D = 80 Vac 3-phase output to pump motor
stator
•
E = ground
Controller-to-pump connector
(applicable to model 969-9435 and 969-9535)
Connection J6 and J7
Accessories and Options Interconnections
J6 and J7 connectors
The 120 Vac, 1 A maximum (independent of line
Voltage) output Voltage is present when the main
power switch is set to 1 position and after START push-
button is pressed and will remain present until a fault
condition is displayed on the front panel display or the
turbopump is stopped.
The connector J6 is a power output for a pump cooling
fan, the connector J7 is for vent device, forepump
connector coils, etc.
The maximum current that can be drawn from J6+J7
is 1 A.
